布局为：A RecyclerView in a Fragment,and the RecyclerView's item is ImageView
Recyclerview的适配器加载内容（我正在使用BaseRecyclerViewAdapterHelper这个框架）：
@Override
protected void convert(BaseViewHolder helper, WechatItem.ResultBean.ListBean item) {
switch (helper.getItemViewType()) {
case WechatItem.ResultBean.ListBean.STYLE_BIG:
helper.setText(R.id.title_wechat_style1, TextUtils.isEmpty(item.getTitle()) ? mContext.getString(R.string.wechat_select) : item.getTitle());
if (!isNotLoad) { //Controls whether the image is loaded
Glide.with(mContext.getApplicationContext())
.load(item.getFirstImg())
.override(mImgWidth, mImgHeight)
.placeholder(R.drawable.lodingview)
.error(R.drawable.errorview)
.crossFade(1000)
.into((ImageView) helper.getView(R.id.img_wechat_style));
}
break;
case WechatItem.ResultBean.ListBean.STYLE_SMALL:
helper.setText(R.id.title_wechat_style2, TextUtils.isEmpty(item.getTitle()) ? mContext.getString(R.string.wechat_select) : item.getTitle());
if (!isNotLoad) {
Glide.with(mContext.getApplicationContext())
.load(item.getFirstImg())
.placeholder(R.drawable.lodingview)
.error(R.drawable.errorview)
.override(mImgWidth / 2, mImgWidth / 2)
.crossFade(1000)
.into((ImageView) helper.getView(R.id.img_wechat_style));
}
break;
default:
break;
}
}
当手机内存很大，并且不会出现OOM时，当手机内存很小时，很容易出现OOM。 当手机内存较大时，并不会出现OOM，当手机内存较小时，很容易出现OOM。

从Log可以清楚地看出，您正在尝试分配比手机更多的字节数。尝试仅在RecyclerView中显示（低质量）缩略图。当用户点击RecyclerView项目时，您可以显示高分辨率图像。
您可以使用以下代码将图片缩小到所需的width和height。
public static Bitmap decodeSampledBitmap(String filePath, int reqWidth, int reqHeight) {
// First decode with inJustDecodeBounds=true to check dimensions
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeFile(filePath, options);
// Calculate inSampleSize
options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight);
// Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;
Bitmap scaled = BitmapFactory.decodeFile(filePath, options);
return scaled;
}
public static int calculateInSampleSize(
BitmapFactory.Options options, int reqWidth, int reqHeight) {
// Raw height and width of image
final int height = options.outHeight;
final int width = options.outWidth;
int inSampleSize = 1;
if (height > reqHeight || width > reqWidth) {
final int halfHeight = height / 2;
final int halfWidth = width / 2;
// Calculate the largest inSampleSize value that is a power of 2 and keeps both
// height and width larger than the requested height and width.
while ((halfHeight / inSampleSize) > reqHeight
&& (halfWidth / inSampleSize) > reqWidth) {
inSampleSize *= 2;
}
}
return inSampleSize;
}
使用功能decodeSampledBitmap缩小图像。

尝试为您的应用程序分配大内存，您可以在manifest.xml文件中的应用程序标记上添加android:largeHeap="true"
